DEMOUNTING/MOUNTING PROCEDURES CAUTION: e tire should be demounted from the wheel using the tire changer manufacturer's instructions. Use the following informa- tion to avoid damage Ensure that the wheel to be fitted is designed for sensor mount. ere should normally be a mark to indicate this. NOTE: If a tire pressure sensor is replaced, it will need to be initiated. See "TPMS reset procedures." e TPMS system is not affected by wheel and tire rotation. TIRE PRESSURE SENSOR CAUTION: Do not use puncture repair fluid, as this can cause the sensor pressure port to block and an incorrect warning to occur. Removal 1) Remove the wheel and tire assembly. CAUTION: Avoid tire/tool contact with the valve while demount- ing the tire. 2) Deflate the tire and remove the balance weights. e tire bead should be broken about 11 inches (30 cm) from the valve inside the wheel. e bead breaker should not be set too deep. Demount should end near the valve. 3) While supporting the sensor with care, remove the valve nut and remove the sensor assembly. CAUTION: e seal and seal washer should not be re-used; remove and discard. 4) While supporting the rear of the valve so there is no movement, remove the seal and seal washer. Installation CAUTION: Avoid bringing the tire pressure sensor in contact with the lubricant. Always handle the tire pressure monitoring sensor carefully. 1) While supporting the rear of the valve so there is no movement, install the new seal and seal washer. 2) Ensure that valve hole and mating face of the wheel are clean. Insert the sensor assembly into the wheel without modifying the angle of the valve stem. e fit should not be tight. CAUTION: Ensure the sensor feet are against the wheel throughout the remainder of the assembly process. 3) Tighten the nut by hand until it is lightly in contact with the wheel (see Figure 3). CAUTION: While tightening the nut, do not exceed the allowed torque. Do not use electric or pneumatic tools. 4) Using a torque wrench, tighten the nut to 35 in.- lbs. (4 N.m). 5) Lubricate the tire bead (not the rim). Do not use excessive lubrication. 6) Start the tire mounting about 5.9 inches (15 cm) from the valve. Move the mounting tool away from the valve. Avoid tire/tool contact with the valve. Finish with the mounting tool near the valve. 7) Adjust inflation pressure of all wheels. Install the valve cap. 8) If installing a new sensor, initiate the tire pressure sensor. See "TPMS reset procedures." ■ Information for this column comes from the tire pressure monitoring systems data in ProDemand®, Mitchell 1's auto repair information software for domestic and import vehicles.

Increase torque smoothly. *In order to achieve a clean break of the stop. Do not exceed allowed torque. Do not use electric or pneumatic tools. Figure 3: Tire pressure sensor installation.
